Educational use
MBA Calc is provided for study, planning, and general calculation support. It is not financial, tax, legal, investment, or other professional advice. Use qualified professionals for decisions that need professional judgment.
Verify important results
We work to reproduce familiar BA II PLUS behavior, but software, device settings, and entered values can affect an outcome. Check material calculations independently before relying on them for coursework, contracts, investments, lending, or other consequential decisions.
Independent software
MBA Calc is independent educational software. It is not affiliated with, endorsed by, or sponsored by Texas Instruments. Product names used to describe calculator compatibility belong to their respective owners.
Software License
MBA Calc software is provided under the standard MIT License governing permission to use and distribute the application.
